Glossary of Shipping Terms


W.M. (W/M) – Abbreviation for "Weight or Measurement;" the basis for assessing freight charges. Also known as "worm." The rate charged under W/M will be whichever produces the highest revenue between the weight of the shipment and the measure of the shipment.

The prior English method was one long ton compared to forty cubic feet.
